To all whom it may concern.-

Be it known that we, ADOLF KRiizNER and FLORIAN TENTSCHERT, engineers, subjects of the Emperor of Austria-Hnugary, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invent ed certain new and useful Improvements in Gar-Starters; and we do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart of this specification.

The object of this invention is to providea simple and efficient device for application to a street-car as a means for assisting the draft, animal in overcoming the inertia of the car and starting the same.

The invention consists, essentially, in a friction device composed of a segmental block or shoe connected with the draft-bar and act; ing either on the periphery or rim of one of the car-wheels or upon a disk secured to the wheel-axle, said friction device being arranged in relation to the wheel or disk as to rotate the latter when power is applied thereto by the draft-animal through said draft-bar.

In the accompanying drawings, Figure 1 is alongitudinal section of acar-truck, showing our improved friction-starter. Fig. 2 is a similar view of a portion of the car-truck on alarger scale to illustrate our invention more clearly. Fig. 3 is a top-plan view of Fig. 1, some of the cross-girts of the truck being broken away to better illustrate the starting devices. Figsft and 5 are views similar to Figs. 1 and 3, showing the starter arranged to act on a disk secured to the wheel axle instead of acting on the wheel itself.

Referring to Figs. 1, 2, and 3 of 'the above drawings, A indicates a car-truck that may be of any usual or preferred construction.

B are the driving-wheels, and O the draftbars, provided with draft-hooks or clevises 0 at each end of the truck.

D D D D are guide-pulleys secured to cross girts 0f the truck and in proper position to guide the draftchains E.

There are provided devices for starting the car whatever may be the direction in which it is to run, and as these devices are alike for both directions of motion it will be sufficient to describe one set of devices, so that the operation of starting may be fully understood.

The draft-chain, after passing over pulleys D D D D, is secured to the outer end of a slightly-bent or angular lever, F, that has its fulcrum upon the car-axle G. At the apex g of the angle of the lever is pivoted a block or shoe, H, the curved face h of which is a segment of the circle or rim of the wheel on which said curved face of the block or shoe bears when acting as a starter.

The lower face, h, of the sector H is rectilinear or square, and when the car is stationary said lower face rests upon the foot is of an angular bracket, K. The position of this.

foot is such that when the lever F has fallen to its lowest point, as in Figs. 1 and 2, the squareface h of the segment H rests on the foot of the bracket K and is tilted back thereby, and thus held out of contact with the driving-wheel.

. To prevent the segment from being tilted entirely over, and also to hold the lever F at the limit of its downward movement, the segment has a tail-piece, h", that projects later- .ally therefrom over the lever-arm, as more plainly shown in Figs. 2 and 5.

It is obvious that when the draft-animal pulls upon the chain E to start the car the leverarm is lifted, the segmental block or shoe H is tilted forward by gravity in contact with the wheel, and as the lever is rotated on its pivot the segmental block or shoe rotates the wheel by frictional contact, thus starting the car. As the lever is a comparatively long one, the power required to start the car is considerably reduced, thus assisting the draft-animal very materially.

L is a stop that projects from the truckframe into the path of the tail-piece h of the block or shoe H, and when the lever F has 5 reached a certain elevation sufficient to impart the necessary impulse to the car-wheel through the block or shoe the stop L cont-acts with the tailpiece h of the block or shoe, and tilts the latter out of contact with the wheel. Here also the complete tilting of the block by the stop L is effectually prevented by the tail-piece k extending over the lever F, as will be readily understood.

In those cars where double brakes are employed, and where it is impracticable to apply the starter to the car-wheels, said starter may be arranged to act upon a disk, 0, rigidly seeured to the wheelaxle, as shown in Figs. 4 and 5.

To adapt the block or shoe H to takea better hold,either on the rim of the car-wheel or the periphery of the disk, its segmental face may be corrugated or otherwise roughened,

and the periphery of the disk may likewise.

be roughened with the block or shoe is applied to act on a disk to increase the frictionalcontact. The contacting surface of the segment may also be roughened when applied to the driving-wheel for increasing the trio tic-nal surface between said wheel and the segment, as will be readily understood.

If desired, a spring, M, Figs. 1 and 4:, may be secured to the lever F, the free end of said spring bearing on a stud or pin, m, projecting from the side of the block or shoe to tilt the latter toward the wheel when carried out of contact with the bracket K, thereby insuring the action of'the segment in case it should not be thrown forward by gravity.

It is obvious that the points at which the power is applied to the wheel or disk and to the lever may be varied without thereby varying the result obtained.

Having now described our invention, what we claim is- 1. In a street-car, mechanism for starting the same, consisting of the angle-lever F,loose- 1y mounted upon one of the wheel-axles, and the segmental shoe H, pivoted to said lever and having a rectilinear face, It, in combination with the bracket K, the draft-bar of the car with which the free end of the lever is connected, and one of the driving-wheels or its specified equivalent, said parts being arranged for operation substantially as described.

2. In a street-ear, the combination, with one of the wheel-axles and driving-wheels, or the specified equivalent of the latter, the angle lever F loosely mounted on said wheel-axle, and the draft-bar of the car with which the free end of the lever is connected, of the segmental shoe H, pivoted to lever F and provided with a projection or tail-piece, h", said-parts being'arranged for operation substantially as and for the purpose specified.

3. In a street-car, the combinatiomwith one of the wheel-axles and driving-wheels, orthe specified equivalent of thelatter, the angular lever F, loosely mounted on said axle, the draft-bar of the car with which the free end of the lever is connected, and the segmental shoe H, provided with a projection or tail piece, [1/2, of a tripping device adapted to engage the tailpiece of the shoe and trip the same, substantially as and forthe purposes specified.

4. The combination, with the draft-bar of a street-car, one of the driving-wheels or its specified equivalent, and one of the wheelaxles, of a lever loosely mounted on said wheelaxle and connected with the draft-bar, a segmental frictionblock or shoe pivoted to the lever and arranged to rotate the wheelaxle by the power exerted on the lever through the draftbar, and a stop to throw the friction device out of operation when the lever has reached the limit of its movement in either direction, as and for the purpose specifled.

In testimony whereof we affix our signatures in presence of two witnesses ADOLF KRUZNER. FLORIAN TENTSGHERT. WVitnesses:
